The easy unit test!
// import
import unit from 'easy-unit.js';
// functions to test
const add = (a, b) => a + b;
const subtract = (a, b) => a - b - 1;
// initiaize Tester
const Tester = new unit();
// initialize Test
const test = Tester.newTest("test");
// assert addition
test.assert("addition", add(1, 2) === 3, "addition failed");
// initialize Test
const test2 = Tester.newTest("test2");
// assert subtraction
test2.assert("subtraction", subtract(1, 2) === -1, "subtraction failed");
// print Results
Tester.printResults(true);You need to initialize a Tester. A Tester will manage your tests. Then you need to create Tests and in each test you can assert. Lets say we got a function x to calculate something in range of 0 to 100. Then we would create a test and in this test we would assert the function with 0, 100 and something inbetween. For each function we create a test with multiple asserts.
